In brief: I day to 1 week
If you have the correct antibiotic it can be very quick.
With the wrong antibiotic it will take a long time. Amoxicillin is good for approximately 75% of the bacteria. Adding Metronidazole (flagyl) takes that up to 99%. Augmentin (amoxicillin and clavulanate) also gets 99% of the bacteria.
